A little man was sad because he had a spaceship but didn't know what to do with it, so he decided to fly to the moon. When he arrived, he wasn't sure what to do so he thought inside his spaceship. He then went outside for a walk and met a dinosaur, with whom he became friends. The little man decided to stay on the moon and live with the dinosaur in a tent from his spaceship, and since then he has been known as "The man on the moon".

The document discusses Java 7 features and provides code examples for migration. It summarizes some of the most relevant features, including multi-catch exceptions, the diamond operator, and NIO.2. While some new features are nice, the document notes that moving to new versions is not automatic and Java 7 has still not seen broad adoption.
10 Golden Social Media Rules for Developer Relations ManagerMarkus Eisele
Social media is great. Being in contact with people from all over the world and being able to help your community from everywhere is nothing short but amazing. Yet, there are a few things to keep in mind to use these tools to their full extend without failing. This session introduces you to some very basic communication skills and walks you through the 10 golden rules in social media.

Un hombre pequeño estaba triste porque tenía una nave espacial pero no sabía qué hacer con ella, así que decidió ir a la luna. Cuando llegó, caminó por la luna hasta que se encontró con un dinosaurio. Como se hicieron amigos, el hombre pequeño decidió vivir en la luna en una tienda en su nave espacial con el dinosaurio. Desde entonces se le conoce como "el hombre de la luna".
One microservice is not enough and microservices should be built as systems. Building a single microservice is generally easy, but building a system of microservices that are integrated is challenging due to increased complexity from deployment, large development teams, and separating functionality from monolithic applications. The Lagom framework is designed to help with building microservice systems by providing an opinionated development environment, service API, and persistence API to address these challenges.
Taking the friction out of microservice frameworks with LagomMarkus Eisele
This document discusses Lagom, a microservices framework for building reactive, distributed systems on the JVM. Lagom promotes building loosely coupled services with explicit boundaries and focuses on asynchronous communication. It provides tools for event sourcing, CQRS, and clustering services for scalability. The document outlines Lagom's approach and provides resources for learning more.
CQRS and Event Sourcing for Java DevelopersMarkus Eisele
This document discusses CQRS and event sourcing patterns for Java developers. It begins with an overview of classical monolithic architectures versus modern microservice architectures. It then contrasts CRUD with CQRS, explaining that CQRS separates reads from writes by using commands for writes and queries for reads. Events evolve from commands and represent things that occurred in the past. The document provides an example implementation using the Lagom framework that demonstrates separating the write side from the read side and persisting events. It emphasizes that with this approach, all state changes are stored as events and the current state can be recreated by replaying events. The document encourages the use of Lagom due to benefits like asynchronous programming, developer productivity, and production readiness.
Nine Neins - where Java EE will never take youMarkus Eisele
Virtual JUG Session: http://www.meetup.com/virtualJUG/events/232052100/
With Microservices taking the software industry by storm, classical Enterprises are forced to re-think what they’ve been doing for almost a decade. It’s not the first time, that technology shocked the well-oiled machine to it’s core. We’ve seen software design paradigms changing over time and also project management methodologies evolving. Old hands might see this as another wave that will gently find it’s way to the shore of daily business. But this time it looks like the influence is bigger than anything we’ve seen before. And the interesting part is, that microservices aren’t new from the core. Talking about compartmentalization and introducing modules belongs to the core skills of architects. Our industry also learned about how to couple services and build them around organizational capabilities.
The really new part in microservices based architectures is the way how truly independent services are distributed and connected back together. Building an individual service is easy with all technologies. Building a system out of many is the real challenge because it introduces us to the problem space of distributed systems. And the difference to classical, centralized infrastructures couldn’t be bigger. There are very little concepts from the old world which still fit into a modern architecture.
And there are more differences between Java EE and distributed and reactive systems. For example, APIs are inherently synchronous, so most Java EE app servers have to scale by adding thread pools as so many things are blocking on I/O (remote JDBC calls, JTA calls, JNDI look ups, even JMS has a lot of synchronous parts). As we know adding thread pools doesn't get you too far in terms of scalability.
This talk is going to explore the nine most important differences between classical middleware and distributed, reactive microservices architectures and explains in which cases the distributed approach takes you, where Java EE never would.
